Singaporean swimmer Joseph Schooling has in recent days been mobbed by jubilant fans, been offered a standing ovation in Parliament and generally treated as a national hero after winning the country's first Olympic gold medal in Rio.

Now, he's decided to mark his historic win in the 100m butterfly in a more permanent fashion - ink.

The 21-year-old swimmer showed off a new tattoo of the Olympic rings on his right bicep at a press conference, with a video of him getting it posted online by the Singapore Swimming Association.
